Hi Gents,I have wired a single M27c801 binswapped (24-->31) running an 8M game with no problems on this board, however I cannot run a game running 2 chips. Can someone please point me in the right direction on how to wire up 2 x 801's please?

If we were willing to just give you wiring instructions, you would have gotten an answer the first time you asked.

ok thank you. I am hoping that you speak on behalf of yourself as others might be willing to go a bit further. Also I'm not sure why your treating this question as a "trade secret" I obviously can use a 2A3B/3M board etc. I have however a few BA3M boards which I would hate to waste so I want to make best use of these if possible.

It isn't a "trade secret". But this kind of question has been beaten to death on here. If you search this forum you'll find numerous other people who made accounts simply to learn how to make repros/bootlegs, and then vanish. Don't take it personally, but people here for the most part are tired of the "I have no experience, please tell me how to make this $$$ game work". If you do a bit of research, videos/tutorials of people showcasing how to make repros are everywhere. Just look over at the racketboy forum to find a bunch of info there.

Getafix (aka retrostage) is right. These questions have been asked many times before. This group is more about --- do your research and while we (this group) won't just hand out an answer, but will do is push you in the right direction so that you can learn what you want to know and maybe get confirmation on your questions at that point.

Without tooting my own horn, there are other new repo pcb boards avail than just those mentioned in the prev post. Good luck!

Basically what you need is a demux, just like this one.It will enable or disable the memory chips according to the address on the input.If you have a MAD chip onboard you probably already have it.Just think a little. the information that was give here is enough, you just need to look at it carefully.If you have some more doubts about the circuit I'm sure people here can help.

Sincerelly, I think combinational logic should be teached at school.It took me a long time to (kind of) learn it... the teachers on the technician course didn't know it very well. Damm!! Even hexadecimal numbering was considered a thing of another world!!I ended learning the basics of it at university, on the architecture "chair" (I don't know how the parts of a university course are called, so I'm using the word "chair" that is what it's called here...).I ended up learning a lot more here in the forums. But still there's a huge amount of things i need/want to learn!
